This page is an index of all Wikimedia Commons' maintenance and Help pages. The following articles contain guidance and information about reading, authoring, and participating in the Commons community.

Mediawiki

The function of MediaWiki itself - the software that Wikimedia Commons runs on - is described at the MediaWiki User's Guide in Meta-Wiki.
If you suspect a software bug, ask for feedback at the village pump, and then report it using the Phabricator bug report system. This is the only way to get MediaWiki developers to notice your bug reports.

The database of Wikimedia Commons can be downloaded. There is currently no dump of the media files available.
